BidDKP
BidDKP is a companion for raids using the WebDKP addon for managing DKP. It provides a graphic interface for DKP functions such as retrieving your dkp and bidding on an item.
The addon monitors chat for raid messages and/or whispers from WebDKP. When it detects a WebDKP message it sets the sender as the DKP target to whisper dkp requests/bids to. Once that person is set, anytime you type /bid to open the bidding box it will automatically whisper that person to get your current DKP and display it in the bidding box.
In the bidding box you can type an amount to bid and click the "Bid" button or you can simply click the "Bid Max" button to send your bid to the person running WebDKP.
I haven't added a minimap button or anything so for now you just type /bid to open it. Obviously that can be macro'ed and put on a button bar for convenience.
